DETACHABLE BRUSH Speciflcation ot Letters Patent.

Patented May'30fi9 11.

Application filed March 9,- 1910. Serial No. 548306.

Ti all 'whom it may portion a Be it known that I, JOHN J. POKORNEY, a citizen of the United States, residing at `No. -429 'East One hundred and sixty-'first street, New York city, State of New York, have invented 'certain new and useful Improvements 'in Detachable Brushes, of which the following is a clear, full, and exact de- Scription.

This 'invention relates to an improved form of a detachable brush and although .the detachable features of this improvement ma be used with any kind of hand brush, as tooth brush,

clothes brush, hair described with a tooth brush. I

In very ex ensive toilet sets the 'articles are often ma e with handles of gold,.silver 20' sentimental and other reasons,

. sirable to keeplong after the brush and other ornamental material, which for are very de ortion orwearing portion is worn out an ready to be thrown away, By having the brushportion detachable as povded for in the present improvement, t 's may be renewed at slight cost when worn' out and the owner may be able to keep the expensive' handle eat number ,of years.

" Other a vantages, such as the 'possibility of using brushes of diferent degrees of` stifl'ness make a 'detachable brush portion very desirable intooth brushes.

Further advantages will appear in the following specificaton which show the preferred embodiment of my invention, the

scope of which will be more particularly pointed out in theagpended claims.

In the drawings, igure 1 shows aperspective view of the entire brush and hane dle assembled. Fig. 2 is a pers ective View of the handle member'detache Fig. 3 is a perspective View of the bristle member N detached. Fig. 4 is a View of the locking member detached. Fig. 5` is a view of a modified form of handle. Fig. 6 is a section along a--a of Fig. '1, showing arrangement of locking member. Fig. 7 is a fragmentary section through b-b Fig. 1 and showing retaining pins. Fig. 8 is a section along 0-?) of Fig. 5 showing the locking member in the modification.

Referring to the drawings, the handle of the brush is indicated at 1 and as shown is of the usual `form and provided with slots 5 near one end, preferably located at opposite sides thereof. It is obvious that these slots ma be at any other locationthan that shown, ut for the ;pur oses of stren th they are preferably locate at opposite sies. These slots also need not necessarily be open at one end, but as shown in Fig. 5 at 5 may be constructed with a larger entrance communicating with a narrower neck portion.

The bristle 'membe'rindicated at 2 is of the usual form, carrying bristles 3 and is provided with upwardly projecting retainng pins 6 which have an enlarged head portion, whereby when' the pins are made to engage thenarrow portion' of the slots 5 or 5 these enlarged heads act to hold` the bristle member 2 and the handle `member 1 together. The upper sides` of these slots are referably countersunk so that the upper en s of the retaming pins will `be below the 'surface of the brush handle; While held together in this way, the members may slide away from eachother as is clear, and to prevent this, the preferred form of locking means shown in the drawings is provided.

Both the bristle member 2 and the handle' member 1 are provided with a plurality of holes, usually twosuch as indicated at 7 in Fig. 3. It is understood that the holes i the handle member 1 register with the holes in the bristle member2 when -these parts are fitted together, in which case a locking member such as a spring wire 4, with downwardly' bent ends may be inserted in these holes and thus prevent the bristlexmember and handle from 'sliding apart. 'The spring r of'the wire retains 'the ,ends of the same down in the holes. To prevent this locking p member 4 .from becomng separated from' the handle, I preferably upset the ends slightly as shown after they have been' inserted through the holes' in the handle. The holes in the bristle member 2 are therefore correspondngly enlarged to receive 'these upset ends as shown in Fig. 6. Thus it is seen that the pins 6 prevent the separation of the members in 'one direction, while the locking member 4 prevents' their sliding apart inthe other'direction, thus forming a complete locking means.

In the modification shown in Figs. 5 and 8 the slots 5 do not extend to the edge of the brush handle l but have an enlarged opening for entrance communicating with a narrow neck retaining portion. The retaining portion of the slot is countersunk i n the same manner as slots to receive the pins 6.

The perforations m handle l to receive the' looking member 4 are also countersuii k at their under side to allow the upset encis of the looking member to be fiush with the untherefore be a serious der surface of the handle member l Since it is almost essential in tooth brushes to present always 'a smooth exterior surface and any projeotion therefrom 'would defeat, I preferably form a groove in 'the back of the' handle, to receive .the longitudinelportion of the wire 4 and as before stated oountersink the Slots,

, ,5 whi'oh'receve the pins 6.

What claim is 1. In ;a brush, the combination of a hanclle 'member', a brush member, means at two `'points of each of said members for securmg -two me bers, anllooking said means compris'ing two headed pins on one member and two laterally extending transverse oountersunkslots in theother member, said meanspermittng separation them together,

in a direction laterally of said means movable relatively to but' inseparable from one of said members, and arranged between the two points of location of said seourin-g means forlocking said members together at two points against any' movement tending to separate said two members in said lateral direction.

2. In a brush, the combination of a handle member, a brush member, means' for removably seouring them together and to oppose separation, of said members in one direction I and lockng'means bere together 'to oppose movement n another 4 for securing said memdireotion, said. looking means comprising registrable holes locatetoward the ende of both members, and a lookingmember having ends for oonjoi'nt insertion in the registrable holes, said looking' member oomprsing a transvers'e bar and headed -extremities separable from one' of said members.

3. As an article -of manufaoture a brush oomprising a hantlle member and a brush member, said members having means for detaohably seourng them together, oomprissaid' ends, having whereby it is made ing seem ing pine.` having enlarged heads on one of said members, the other member having countersunk Slots to receive said pins, wherei by the heads of 'said pine may be below the surface of said slotte member, both of said members having wplurality'o holes adapted to be in registration and aloeking member having bent ends eXtending through ancl retained in one member,

said ends v adaptedto be inserted in the second member for looking saidmembers together, said pine and looking member all being within .the surface of said handle anbrush member when the parts of the brush are in position for use.

4:. In a brush, the oombination of a handle member, a brush member, means at two points of each of said members for seouring them together, said means oomprising pins on one member and laterally extending the other member, saidtransverse Slots in means permitting separation in a direction laterally of said two mem'hers, and looking means movable relatively to but inseparable from. one of sai& members and arranged between the points of location of said seouring Signed at New York city, Y. this 26th day of February 1910.
